elrich, this happened to both of us ... our SSN locked. Therefore, we did not receive our SS checks. It was because we had not received the forms they mailed us that need to be filled out saying we were still alive and living outside the U.S. At least then the office was open in Guadalajara and they handled it all by email and we got our SS checks they had been holding in about 3 weeks.
We have not received a stimulus check yet either. When I went to the website to enter our banking information it said to not fill it out if we received our SS checks by direct deposit as they would use that information. When I checked again it said we would receive payment on May 15 which came and went. I checked again and it says that they have mailed our checks to the address on file ... which, of course, is here. I don't know if we will ever see those checks or not. Half the time our mail is delivered to someone else's house and part of the time it is thrown out in the yard. We found our mail and a neighbor's mail once sitting on the curb down the street while taking a walk.
